Hi,

I was wondering if anyone knew where to look up expressions for the computational complexity of these 2 matlab functions: eig and pinv.

Thank you in advance, Ina

The computational cost of eig should be O(N^3) with N dimension of the matrix

If I recall, in theory it could be a little better, closer to N^e -- but I have no idea which of the optimizations are implemented.
